Application filed August 6, 1917.

To all whom may concern s Be it known 'that l, HARRY LEMISZCZAK, asubject o the Emperor oi Austria, resident oi Yonkers, countyv oflVestohester, and- State oi New York, have invented certain neuv anduseful linprovenients in Autisubinerme Devices. of which the following1s a i specification.

This invention, relates to improven'lents in protecting devices for thehulls of vessels, and has as its special object the provision of meanswhich may rapidly. be suspended iironi the hull of a vessel and arrangedto iorni an effective guard against torpedoes and the lilre, Which areprevented from causnre; damage to the vessel.

ri"his object attained by the novel construction and combination oi'parts here after o escribed and shown in the accom-A panj/'ine' dIavvings, iorniinga material part oi this disclosure, and in which-Figure l. is a side. elevational View of a conventional type of vesselindicating the application of the invention.`

Fig'. is a top plan view illustrating the application of guard plaies toa vessel.

. ,il 8 is a transverse vertical vi W talren 8 8 of Fig. Q and 9 is aperspective vieu.' looking from r side oi one oiz the guard plates. iisit obi/'ions that au armor plate disposed at a distance from the Wallsoi' the will iin; de its movement through is'deei. l advisable toprovide plates in rorins which may be readily attached to the gunwalesof a vessel in time of need. and which ma;V normally be carried.' upon'the v Alsel itself.

'The prese; 'Wen on comprises a plu rectangular' arinor l0, adapten tobe suspended by straps the saine being,1 hooked-shaped and adapted toover the top e of the vessel so as to han@ pendently beside the thesaine Specification of Letters Patent.

hull 13, and in order to provides desirable degree of resilience to theplate it), a plurality of arcuate or elliptical springs l5 are attachedby rivets 16 to the plateupon one side, the springs being disposed oneabove the other in a vertical row in such manner that the opposite sideof the spring will make contact with the vessel hull 13, so that if theplate l receives the shock or impact of a projectile, a certain amountof resilience is obtainable, tending to cushion the blow transmitted tothe walls of the vessel, and it will be obvious that the armor platesare substantially straight along-'the sides and bent in conformity withthe outline of the vessel at the stern and bow thereof.

In place of the elliptical spring l it may be preferred to use thedevice shown in Figs. 5 and G, in which a pluralityv of resilientcontact elements 20 are irinly engaged to the plates 1S the edges 2l`and 22 of the plate being beveled and arranged in vertical rows in themanner of the scales of a fish, the edge of one slightlyv overlappingthat of the sueceeding plate.

In order t0 hold these plates in relation with the sides 13 ot' thevessel, a plurality of bolts 23,; are alixed in the Walls of the vessel,the' saine extending through the plates 18 and secured in position bymeans of the nuts 24, there being disposed between the walls 13 of thevessel and the plates 1S, spira-ily coiled compression springs 25, thesaine e circling, the Shanks of the bolts 23.

ln mis forni, each of 'the plates is independently suspended and so heldas `to be able to nieve in toward the vessel until the springs andresilient elements have absorbed the shock or blow.

iin 7 to 9 inclusive a soniewha-te simiM lar arrangement of sectionalplates is iii-:iicatcd, each oi' the plates 30 having beveled Ydges anda central opening 82, receptive of the reduced stein 35, of posts 36,supported by brackets 37, secured by screws 38 or the like to the walli3 of the vessel, the posts l'izwing` shoulders against which the innerside of the gllard or armor plates ulalie contact and which are held inposilion by means of the nuts lli), all of these several guard or armorplates being' Ytorined with rigid projections l2 at their corners, theinner rounded points ci which make contact with the vessel hull,presenting in eil'ect a substantial, rigid outer casing for the vessel.

From the foregoing it will be seen that a .substantial arrangement forprotecting the hulls of vessels has been disclosed.

Having thus described my invention what claim as new and desire tosecure 'by Letters Patent, is

In a sliips armor of the character described, the combination of aplurality of centrallyT perforated plates having beveled edges, withposts adapted to space and hold said plates apart from the ships hull,reduced stems on said posts passing through the perforations of saidplates, brackets on lessee@ HARRY l'iEMSZGZAK.
